Let's divide 48487930 by 4
We're looking to find how many times 4 goes into 48487930.

On to step 1:
When dividing 4 by 4, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 4 away from 4, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 4

Let's proceed to step 2:
4 can be fit into 8 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 8 from 8 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 4

Moving on to step 3:
The number 4 fits into 4 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 121.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 4

Step 4:
4 goes into 8 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 1212.0
Subtract 8 from 8 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 4

Step 5:
When dividing 7 by 4, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 12121.0
Subtracting 4 from 7 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 4

On to step 6:
If we divide 39 by 4, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 121219.0
The remainder is 3 after subtracting 36 from 39.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 4

Advancing to step 7:
If we divide 33 by 4, we get 8 and a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1212198.0
Subtract 32 from 33 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 4

Advancing to step 8:
If we divide 10 by 4, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 12121982.0
Subtract 8 from 10 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12121982.5
Deduct 20 from 20 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12121982.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12121982.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 12121982.5 with a balance of 0.0.
